MOTOR MOUNTING.

Application filed May 20,

This invention relates to improvements in motor mountings, particularlyadapted for attaching electric motors to sewing machine heads fordriving the machine hand wheels.

It is one of the objects of the present invention to provide a motormounting for a sewing machine head to so hold the motor that the pulleywheel. thereof will be yieldingly held in frictional engagement with themachine hand wheel.

A further object of the invention is to provide a motor mounting of theclass de scribed non-removably engaging both the head and the motor.

A further object of the invention is. to provide a motor mounting of theclass described adapted for ready attachment to the side of the head ofany of the well-known makes of sewing machines.

A further object of the invention is to provide a motor mounting forsewing machine heads which is of very simple construction, isinexpensive to manufacture, is strong and durable, and is well adaptedfor the purpose set forth.

With the above and other objects in view the invention consists of theimproved motor mounting and its parts and combinations as set forth inthe claims, and all equivalents thereof.

In the accompanying'drawing in which the same reference charactersindicate the same parts in both of the views:

Fig. 1 is an end view of a sewing machine head having an electric motorattached thereto by means of the improved motor mounting; and

Fig. 2 is a side view thereof.

Referring now more particularly to the drawing, it will appear that thenumeral 5 indicates the head portion of a sewing machine having a handwheel 6 mounted at its end.

Adapted to be secured to the side of the head is a small flat typeelectric motor 7 and 1926. Serial- No. 110,360.

the securing means or mounting comprise a. plurality of legs 8, 9 and10, bent as shown, and formed of spring steel. The inner ends of all ofthe legs are secured to the motor by screws, while the outer ends ofonly the legs to 8 and 10 are attached to the head by screws. All of thelegs are of such a length that the pulley wheel 11 of the motoryieldingly bears against the hand wheel to frictionally drive the same.The yieldability of the legs and the free end portion of the side leg 9allows the motor to give when necessary to compensate for irregularitiesin the motion of the hand wheel.

From the foregoing description it will be seen that the improved motormounting is of very simple and novel construction and is well adaptedfor the purpose described.

What is claimed as the invention is:

1. The combination with a sewing machine 55 head having a hand wheel, ofa motor having a pulley wheel adapted for yielding fri c tionalengagement with the periphery of the hand wheel, a yieldable stripsecured to the lower portion of the motor and toa lower !0 portion ofthe head, a yieldable strip secured 1 to the upper portion of the motorand to an upper portion of the head, and a'yieldable strip secured to anintermediate portion of the motor and non-fixedly bearing against anintermediate portion of the head. 2. The combination with a sewingmachine having a hand wheel, of a motor having a. pulley wheel adaptedfor yielding frictional engagement with the periphery of the hand wheel,a plurality of thin yieldable members interposed between the motor andthe sewing machine head at different points and being secured both tothe head and to the motor,

and another thin yieldable member secured only to the motor andnon-fixedly bearing against the head.

In testimony whereof, Iatfix my signature.
